Summary: Solid-state lithium metal batteries (SSLMBs) have potential for high safety and energy density, but the growth of lithium dendrite in solid electrolytes limits their practical applications. This study develops a simple heat treatment method to revive and recycle garnet oxide electrolytes with Li dendrite penetration. The recovered garnet electrolyte shows higher relative density, enhanced ionic conductivity, and improved critical current density compared to the pristine one. Thermal healing is attributed to the reaction products between dendritic Li metal and air, contributing to further densification of garnet electrolytes during heat treatment.

Summary: In this study, a hydrophobic CFx film was introduced on the LLZTO surface for high-performance solid-state batteries. The CFx film provided a Li2CO3-free surface and formed a LiC-LiF mixed conductive interlayer with the Li metal, resulting in low interfacial resistance and improved Li+ conduction. The CFx-LLZTO-based cells exhibited high critical current density and stable cycling life, and the Li/LiFePO4 cells with CFx-LLZTO showed improved cycling and rate performance.

Summary: In this study, a poly(ether block amide) (PEBA) based polymer electrolyte with lithium bis-(trifluoromethanesulfonyl)imide (LiTFSI) as the Li salt is developed, which possesses good ion conductivity and suppresses the growth of Li dendrites. The electrolyte provides abundant amide groups to activate TFSI- anions and further enriches lithium fluoride (LiF) content in the SEI layer, resulting in improved cyclability and long-life span of the full-cell battery. Therefore, the PEBA based electrolyte shows great potential for solid-state lithium metal batteries.

Summary: Random amphiphilic copolymers containing a large fraction of ureidopyrimidinone (UPy) were synthesized to produce antifreeze and dynamic hydrogels. The directional packing of UPy-UPy dimers provides nanosized aggregates with narrow gap distances, inhibiting water crystallization by the confinement effect. The temperature-dependent dynamics of UPy allow the hydrogels to form a frozen structure at lower temperatures and exhibit injectability and self-healing properties at room temperature, with negligible cytotoxicity expanding the potential applications in drug storage and cell cryopreservation.

Summary: SiCf/SiC composites fabricated through a two-step pyrolysis process and LSI process exhibit increased density, reduced porosity, and higher flexural strength compared to those fabricated through a one-step pyrolysis process. Among specimens processed with the same two-step pyrolysis, those subjected to LSI at 1500 degrees Celsius show significantly higher flexural strength than those at 1450 or 1550 degrees. Additionally, mechanical properties of SiCf/SiC specimens processed at 1500 degrees Celsius are superior to those at 1550 degrees Celsius despite similar porosity and density due to the rapid degradation of Tyranno-S grade SiC fibers at higher LSI process temperatures.
